SCC to initiate Smart Grid Roadmap implementation

Offshore Wind-to-Hydrogen Integration enables green hydrogen by embedding an electrolyzer in offshore turbines. Siemens Gamesa and Siemens Energy align under H2Mare to decarbonize industry, advance the Paris Agreement, and unlock scalable, off-grid renewable production.

Key Points

A method integrating electrolyzers into offshore wind turbines to generate green hydrogen and reduce carbon emissions.

✅ Integrated electrolyzer at turbine base for off-grid operation

✅ Enables scalable, cost-efficient green hydrogen production

✅ Supports decarbonization targets under Paris Agreement

To reach the Paris Agreement goals, the world will need vast amounts of green hydrogen and, with offshore wind growth accelerating, wind will provide a large portion of the power needed for its production.

Siemens Gamesa and Siemens Energy announced today that they are joining forces combining their ongoing wind-to-hydrogen developments to address one of the major challenges of our decade - decarbonizing the economy to solve the climate crisis.

The companies are contributing with their developments to an innovative solution that fully integrates an electrolyzer into an offshore wind turbine as a single synchronized system to directly produce green hydrogen. The companies intend to provide a full-scale offshore demonstration of the solution by 2025/2026. The German Federal Ministry of Education and Research, reflecting Germany's clean energy progress, announced today that the developments can be implemented as part of the ideas competition 'Hydrogen Republic of Germany'.

'Our more than 30 years of experience and leadership in the offshore wind industry, coupled with Siemens Energy's expertise in electrolyzers, brings together brilliant minds and cutting-edge technologies to address the climate crisis. Our wind turbines play a huge role in the decarbonization of the global energy system, and the potential of wind to hydrogen means that we can do this for hard-to-abate industries too. It makes me very proud that our people are a part of shaping a greener future,' said Andreas Nauen, Siemens Gamesa CEO.

Christian Bruch, CEO of Siemens Energy, explains: 'Together with Siemens Gamesa, we are in a unique position to develop this game changing solution. We are the company that can leverage its highly flexible electrolyzer technology and create and redefine the future of sustainable offshore energy production. With these developments, the potential of regions with abundant offshore wind, such as the UK offshore wind sector, will become accessible for the hydrogen economy. It is a prime example of enabling us to store and transport wind energy, thus reducing the carbon footprint of economy.'

Over a time frame of five years, Siemens Gamesa plans to invest EUR 80 million and Siemens Energy is targeting to invest EUR 40 million in the developments. Siemens Gamesa will adapt its development of the world's most powerful turbine, the SG 14-222 DD offshore wind turbine to integrate an electrolysis system seamlessly into the turbine's operations. By leveraging Siemens Gamesa's intricate knowledge and decades of experience with offshore wind, electric losses are reduced to a minimum, while a modular approach ensures a reliable and efficient operational set-up for a scalable offshore wind-to-hydrogen solution. Siemens Energy will develop a new electrolysis product to not only meet the needs of the harsh maritime offshore environment and be in perfect sync with the wind turbine, but also to create a new competitive benchmark for green hydrogen.

The ultimate fully integrated offshore wind-to-hydrogen solution will produce green hydrogen using an electrolyzer array located at the base of the offshore wind turbine tower, blazing a trail towards offshore hydrogen production. The solution will lower the cost of hydrogen by being able to run off grid, much like solar-powered hydrogen in Dubai showcases for desert environments, opening up more and better wind sites. The companies' developments will serve as a test bed for making large-scale, cost-efficient hydrogen production a reality and will prove the feasibility of reliable, effective implementation of wind turbines in systems for producing hydrogen from renewable energy.

The developments are part of the H2Mare initiative which is a lighthouse project likely to be supported by the German Federal Ministry of Education and Research ideas competition 'Hydrogen Republic of Germany'. The H2mare initiative under the consortium lead of Siemens Energy is a modular project consisting of multiple sub-projects to which more than 30 partners from industry, institutes and academia are contributing. Siemens Energy and Siemens Gamesa will contribute to the H2Mare initiative with their own developments in separate modular building blocks.

About hydrogen and its role in the green energy transition

Currently 80 million tons of hydrogen are produced each year and production is expected to increase by about 20 million tons by 2030. Just 1% of that hydrogen is currently generated from green energy sources. The bulk is obtained from natural gas and coal, emitting 830 million tons of CO2 per year, more than the entire nation of Germany or the global shipping industry. Replacing this current polluting consumption would require 820 GW of wind generating capacity, 26% more than the current global installed wind capacity. Looking further ahead, many studies suggest that by 2050 production will have grown to about 500 million tons, with a significant shift to green hydrogen already signaled by projects like Brazil's green hydrogen plant now underway. The expected growth will require between 1,000 GW and 4,000 GW of renewable capacity by 2050 to meet demand, and in the U.S. initiatives like DOE hydrogen hubs aim to catalyze this build-out, which highlights the vast potential for growth in wind power.

Egypt-ENI Hydrogen MoU outlines joint feasibility studies for green and blue hydrogen using renewable energy, carbon capture, and CO2 storage, targeting domestic demand, exports, and net-zero goals within Egypt's energy transition.

Key Points

A pact to study green and blue hydrogen in Egypt, leveraging renewables, CO2 storage, and export/demand pathways.

✅ Feasibility study for green and blue hydrogen projects

✅ Uses renewables, SMR, carbon capture, and CO2 storage

✅ Targets local demand, exports, and net-zero alignment

The Egyptian Electricity Holding Company (EEHC) and the Egyptian Natural Gas Holding Company (EGAS) signed a memorandum of understanding (MoU) with the Italian energy giant Eni to assess the technical and commercial feasibility of green and blue hydrogen production projects in Egypt, which many see as central to power companies' future strategies worldwide today.

Under the MoU, a study will be conducted to assess joint projects for the production of green hydrogen using electricity generated from renewable energy and supported by regional electricity interconnections where relevant, and blue hydrogen using the storage of CO2 in depleted natural gas fields, according to a statement by the Ministry of Petroleum on Thursday.

The study will also estimate the potential local market consumption of hydrogen and export opportunities, taking cues from Ontario's hydrogen economy proposal to align electricity rates for growth.

This agreement is part of Eni's objective to achieve zero net emissions by 2050 and Egypt's strategy towards diversifying the energy mix and developing hydrogen projects in collaboration with major international companies, taking note of Italy's green hydrogen initiatives in Sicily as a comparable effort.

It signed the deal with Egyptian Natural Gas Holding (EGAS) and Egyptian Electricity Holding Co. (EEHC).

The companies will carry out a joint study on producing renewable energy powered green hydrogen, informed by electrolyzer investments in similar projects, where applicable. They will also work on blue hydrogen. This involves reforming natural gas and capturing the resulting CO2, in this instance in depleted natural gas fields.

The study will also consider domestic hydrogen use and export options, including funding models like the Hydrogen Innovation Fund now in Ontario.

Eni said the MoU was in line with its plans to eliminate net emissions and emissions cancel emission intensity by 2050. The company noted the agreement was in line with Egypt’s plan for the energy transition, in which it pursues hydrogen plans with major international companies, alongside broader clean-tech collaboration such as Tesla cooperation discussions in Dubai, to accelerate progress.

Maritime Electric Hurricane Irma Response details utility crews aiding Turks and Caicos with power restoration, storm recovery, debris removal, and essential services, coordinated with Fortis Inc., despite limited equipment, heat, and over 1,000 downed poles.

Key Points

A utility mission restoring power and essential services in Turks and Caicos after Irma, led by Maritime Electric.

✅ Over 1,000 poles down; crews climbing without bucket trucks

✅ Restoring hospitals, water, and communications first

✅ Fortis Inc. coordination; 2-3 week deployment with follow-on crews

Maritime Electric has sent a crew to help in the clean up and power restoration of Turks and Caicos after the Caribbean island was hit by Hurricane Irma, a storm that also saw FPL's massive response across Florida.

They arrived earlier this week and are working on removing debris and equipment so when supplies arrive, power can be brought back online, and similar mutual aid deployments, including Canadian crews to Florida, have been underway as well.

Fortis Inc., the parent company for Maritime Electric operates a utility in Turks and Caicos.

Kim Griffin, spokesperson for Maritime Electric, said there are over 1000 poles that were brought down by the storm, mirroring Florida restoration timelines reported elsewhere.

"It's really an intense storm recovery," she said. 'Good spirits'

The crew is working with less heavy equipment than they are used to, climbing poles instead of using bucket trucks, in hot and humid weather.

Griffin said their focus is getting essential services restored as quckly as possible, similar to progress in Puerto Rico's restoration efforts following recent hurricanes.

The crew will be there for two or three weeks and Griffin said Maritime Electric may send another group, as seen with Ontario's deployment to Florida, to continue the job.

She said the team has been well received and is in "good spirits."

"The people around them have been very positive that they're there," she said.

"They've said it's just been overwhelming how kind and generous the people have been to them."

Proton Conducting Fuel Cells enable reversible hydrogen energy storage, coupling electrolyzers and fuel cells with ceramic catalysts and proton-conducting membranes to convert wind and solar electricity into fuel and back to reliable grid power.

Key Points

Proton conducting fuel cells store renewable power as hydrogen and generate electricity using reversible catalysts.

✅ Reversible electrolysis and fuel-cell operation in one device

✅ Ceramic air electrodes hit up to 98% splitting efficiency

✅ Scalable path to low-cost grid energy storage with hydrogen

If we want a shot at transitioning to renewable energy, we’ll need one crucial thing: technologies that can convert electricity from wind, sun, and even electricity from raindrops into a chemical fuel for storage and vice versa. Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.

The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8% of all power in the United States; in 2017, that number was 8%, according to the U.S. Energy Information Administration. But the demand for electricity often doesn’t match the supply from solar and wind, a key reason why the U.S. grid isn't 100% renewable today. In sunny California, for example, solar panels regularly produce more power than needed in the middle of the day, but none at night, after most workers and students return home.

Some utilities are beginning to install massive banks of cheaper solar batteries in hopes of storing excess energy and evening out the balance sheet. But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel. A second set of devices called fuel cells can then convert that hydrogen back to electricity to power cars, trucks, and buses, or to feed it to the grid.

But commercial electrolyzers and fuel cells use different catalysts to speed up the two reactions, meaning a single device can’t do both jobs. To get around this, researchers have been experimenting with a newer type of fuel cell, called a proton conducting fuel cell (PCFC), which can make fuel or convert it back into electricity using just one set of catalysts.

PCFCs consist of two electrodes separated by a membrane that allows protons across. At the first electrode, known as the air electrode, steam and electricity are fed into a ceramic catalyst, which splits the steam’s water molecules into positively charged hydrogen ions (protons), electrons, and oxygen molecules. The electrons travel through an external wire to the second electrode—the fuel electrode—where they meet up with the protons that crossed through the membrane. There, a nickel-based catalyst stitches them together to make hydrogen gas (H2). In previous PCFCs, the nickel catalysts performed well, but the ceramic catalysts were inefficient, using less than 70% of the electricity to split the water molecules. Much of the energy was lost as heat.

Now, two research teams have made key strides in improving this efficiency, and a new fuel cell concept brings biological design ideas into the mix. They both focused on making improvements to the air electrode, because the nickel-based fuel electrode did a good enough job. In January, researchers led by chemist Sossina Haile at Northwestern University in Evanston, Illinois, reported in Energy & Environmental Science that they came up with a fuel electrode made from a ceramic alloy containing six elements that harnessed 76% of its electricity to split water molecules. And in today’s issue of Nature Energy, Ryan O’Hayre, a chemist at the Colorado School of Mines in Golden, reports that his team has done one better. Their ceramic alloy electrode, made up of five elements, harnesses as much as 98% of the energy it’s fed to split water.

When both teams run their setups in reverse, the fuel electrode splits H2 molecules into protons and electrons. The electrons travel through an external wire to the air electrode—providing electricity to power devices. When they reach the electrode, they combine with oxygen from the air and protons that crossed back over the membrane to produce water.

The O’Hayre group’s latest work is “impressive,” Haile says. “The electricity you are putting in is making H2 and not heating up your system. They did a really good job with that.” Still, she cautions, both her new device and the one from the O’Hayre lab are small laboratory demonstrations. For the technology to have a societal impact, researchers will need to scale up the button-size devices, a process that typically reduces performance. If engineers can make that happen, the cost of storing renewable energy could drop precipitously, thereby moving us closer to cheap abundant electricity at scale, helping utilities do away with their dependence on fossil fuels.

Alberta Rate of Last Resort streamlines electricity regulations to stabilize the default rate, curb price volatility, and protect rural communities, low-income households, and seniors while preserving competition in the province's energy market.

Key Points

Alberta's Rate of Last Resort sets biennial default electricity prices, curbing volatility and protecting customers.

✅ Biennial default rate to limit price spikes

✅ Focus on rural, senior, and low-income customers

✅ Encourages competitive contracts and market stability

The Alberta government is overhauling its electricity regulations as part of a market overhaul aimed at reducing spikes in electricity prices for consumers and businesses. The new rules, set to be introduced this spring, are intended to stabilize the default electricity rate paid by many Albertans.

Background on the Rate of Last Resort

Albertans currently have the option to sign up for competitive contracts with electricity providers. These contracts can sometimes offer lower rates than the default electricity rate, officially known as the Regulated Rate Option (RRO). However, these competitive rates can fluctuate significantly. Currently, those unable to secure these contracts or those who are on the default rate are experiencing rising electricity prices and high levels of price volatility.

To address this, the Alberta government is renaming the default rate as the Rate of Last Resort designation (RoLR) under the new framework. This aims to reduce the sense of security that some consumers might associate with the current name, which the government feels is misleading.

Key Changes Under New Regulations

The new regulations, which include proposed market changes that affect pricing, focus on:

• Price Stabilization: Default electricity rates will be set every two years for each utility provider, providing greater predictability by enabling a consumer price cap and reducing the potential for extreme price swings.
• Rural and Underserved Communities: The changes are intended to particularly benefit rural Albertans and those on the default rate, including low-income individuals and seniors. These groups often lack access to the competitive rates offered by some providers and have been disproportionately affected by recent price increases.
• Promoting Economic Stability: The goal is to lower the cost of utilities for all Albertans, leading to overall lower costs of living and doing business. The government anticipates these changes will create a more attractive environment for investment and job creation.

Opposition Views

Critics argue that limiting the flexibility of prices for the default electricity rate could interfere with market dynamics and stifle market competition among providers. Some worry it could ultimately lead to higher prices in the long term. Others advocate directly subsidizing low-income households rather than introducing broad price controls.

Balancing Affordability and the Market

The Alberta government maintains that the proposed changes will strike a balance between ensuring affordable electricity for vulnerable Albertans and preserving a competitive energy market. Provincial officials emphasize that the new regulations should not deter consumers from seeking out competitive rates if they choose to.

The Path Ahead

The new electricity regulations are part of the Alberta government's broader Affordable Utilities Program, alongside electricity policy changes across the province. The legislation is expected to be introduced and debated in the provincial legislature this spring with the potential of coming into effect later in the year. Experts expect these changes will significantly impact the Alberta electricity market and ignite further discussion about how best to manage rising utility costs for consumers and businesses.

Alberta Renewable Energy Procurement is surging as corporate PPAs drive wind and solar growth, with the Pembina Institute and the Business Renewables Centre linking buyers and developers in Alberta's energy-only market near Medicine Hat.

Key Points

A market-led approach where corporations use PPAs to secure wind and solar power from Alberta projects.

✅ Corporate PPAs de-risk projects and lock in clean power.

✅ Alberta's energy-only market enables efficient transactions.

✅ Skilled workforce supports wind, solar, legal, and financing.

Alberta has big potential when it comes to providing renewable energy, advocates say.

The Pembina Institute says the practice of corporations committing to buy renewable energy is just taking off in Canada, and Alberta has both the energy sector and the skilled workforce to provide it.

Earlier this week, a company owned by U.S. billionaire Warren Buffett announced a large new wind farm near Medicine Hat. It has a buyer for the power.

Sara Hastings-Simon, director of the Pembina's Business Renewables Centre, says this is part of a trend.

"We're talking about the practice of corporate institutions purchasing renewables to meet their own electricity demand. And this is a really well-established driver for renewable energy development in the U.S.," she said. "You may be hearing headlines like Google, Apple and others that are buying renewables and we're helping to bring this practice to Canada."

The Business Renewables Centre (BRC) is a not-for-profit working to accelerate corporate and institutional procurement of renewables in Canada. The group held its inaugural all members event in Calgary on Thursday.

Hastings-Simon says shareholders and investors are encouraging more use of solar and wind power in Canada.

"We have over 10 gigawatts of renewable energy projects in the pipeline that are ready for buyers. And so we see multinational companies coming to Canada to start to procure here, as well as Canadian companies understanding that this is an opportunity for them as well," Hastings-Simon said.

"It's really exciting to see business interests driving renewable energy development."

Hastings-Simon says renewable procurement could help dispel the narrative that it's all about oil and gas in Alberta by highlighting Alberta as a powerhouse for both green energy and fossil fuels in Canada.

She says the practice started with a handful of tech companies in the U.S. and has become more mainstream there, even as Canada remains a solar laggard to some observers, with more and more large companies wanting to reduce their energy footprint.

He says his U.S.-based organization has been working for years to speed up and expand the renewables market for companies that want to address their own sustainability.

"We try and make that a little bit easier by building out a community that can help to really reinforce each other, share lessons learned, best practices and then drive for transactions to have actual material impact worldwide," he said.

"We're really excited to be working with the Pembina group and the BRC Canada team," he said. "We feel our best value for this is just to support them with our experiences and lessons. They've been basically doing the same thing for many years helping to grow and grow and cultivate the market."

Porter says Alberta's market is more than ready.

"There are some precedent transactions already so people know it can work," he said. "The way Alberta is structured, being an energy-only market is useful. And I think that there is a strong ecosystem of both budget developers and service providers … that can really help these transactions get over the line."

As procurement ramps up, Hastings-Simon says Alberta already has the skilled workers needed to fill renewable energy jobs across the province.

"We have a lot of the knowledge that's needed, and that's everybody from the construction down through the legal and financing — all those pieces of building big projects," she said. "We are seeing increasing interest in people that want to become involved in that industry, and so there is increasing demand for training in things like solar power installation and wind technicians."

Hastings-Simon predicts an increase in demand for both the services and the workers.

"As this industry ramps up, we're going to need to have more workers that are active in those areas," she said. "So I think we can see a very nice increase — both the demand and the number of folks that are able to work in this field."
